Notebook: AFC West Road Warriors

For just the fourth time in franchise history, the Broncos have gone undefeated on the road within their division.

ENGLEWOOD, Colo. -- After Sunday's win in San Diego, the Broncos have now beaten every AFC West opponent on the road this season.

It marks just the fourth time in Broncos history the team has gone undefeated on the road within the division.

The other three years were 1977, 1998 and 2009 -- the first two of which were Super Bowl seasons.

“I think it’s a mindset, something that we’ve stressed as a staff," Head Coach John Fox said of winning away from Sports Authority Field at Mile High. "To go on the road any time is a difficult duty. It’s just getting guys in that routine, getting them with that mindset, what it’s like to go into foreign territory. It’s something that I think our guys are starting to develop some confidence in.”

The latest win put the Broncos at 6-5, still a game out of first place in the division. but the team isn't worried about the standings quite yet

“Right now, we’re focusing on us, what we’ve got to do each week, each day, each play," Fox said. "We don’t want to be distracted by all the noise; we just try to stay focused on what we’re doing.”

TEBOW CONTINUES TO IMPROVE

In his weekly Monday press conference, Fox was asked whether Tim Tebow made significant improvement throwing the ball in the win against the Chargers.

"I think that's a fair assessment," he said.

“He’s getting a better feel, and like the old adage, the more you do it, the better you get. I think (Quarterbacks Coach) Adam Gase and (Offensive Coordinator) Mike McCoy have done a terrific job with him before practice, after practice, and he’s done a terrific job of being willing to do the extra work. That’s part of being a pro, and he’s proved to be a good one.”

Fox pointed to Tebow's 39-yard completion to Eric Decker on third-and-11 on the game-tying drive as an example of the quarterback's improvement.

“There are progressions -- I think with each week he understands that better and knows better how to read defenses," Fox said. "He’s done a good job of throwing these balls with each week. I see improvement in the passing game. As that develops, we’ll be better for it.”

While he improves as a passer, Tebow has continued to produce as a runner. He ran 22 times on Sunday -- the most by an NFL quarterback since at least 1950, when the statistic began being tracked -- picking up 67 yards.

Fox said that while he's concerned about every player's durability taking a lot of reps, he won't put a set number on runs he's comfortable with Tebow making.

“In a lot of ways, the quarterback is more exposed in the pass game than he is in the run game, because you can’t defend yourself," he said.

Decker said the team has confidence that the quarterback can handle the load.

"We just have to keep executing and know that if he has to carry the ball that many times, he’s durable enough to do it," he said.

VAUGHN TO IR; MOHAMED, McCARTHY TO ACTIVE ROSTER

This morning, Fox called cornerback Cassius Vaughn's ankle injury "significant enough," but the team was still determining the course to take with the second-year pro.

Monday afternoon, the team placed Vaughn on injured reserve.

That meant two spots were available on the active roster, and the club filled them by signing safety Kyle McCarthy and linebacker Mike Mohamed from the practice squad.

McCarthy tweeted about the transaction shortly thereafter.

"Thank you for all the support throughout the last year!" he wrote. "Excited for things to come!"
